- self-bound book, magazine, pamphlet, or like ar- 4 Glaims;

This invention relates to improvements in binding devices for books,magazines, pamphlets, etc}, and aims to provide a binding for sucharticles in which their leaves, pages or sheets are wholly self-bindingor self-securing without the sac ri-,

fice of appearances, efficiency and durability?v hence, insuring aminimum of elements or parts of the bound and finished work.

It is also an object of the invention to provide improvements in bookand like article bindings by means of which the leaves, pages or sheetsthereof can be positively secured or bound 'in assembled relation and,at will, so adjusted-:or actuated as to permit convenient removal ofoneor more thereof, then re-engaged with theremaining leaves, pages orsheets of the assembly to positively secure them in their originalrelationship.

Furthermore, it is an object of the invention to provide a bindingdevice of the herein stated character which, by reason of itsconstruction, will afford considerable economies through the eliminationof and, hence, conservation of metals and certain other materials nowbeing utilized in the production of binding devices and in the bindingof books, catalogs, magazines, pamphlets andsimilar articles.

Other objects of the invention will be in part obvious and in partpointed out hereinafter;

In order that the invention and its mode of operation may be readilyunderstood by those skilled in the art to which it appertains, I have inthe accompanying drawing and the detailed description based thereupon,set out several embodiments of my invention.

In the drawing:

Figure l is a side elevation of a book, magazine, pamphlet or likearticle bound in accordance with my invention. I

Figure 2 is an enlarged fragmentary transverse section taken on the line2-2 of Figure 1, looking in the direction in which the arrows point.

Figure 3 is a similar section taken on the hue 3-3 of Figure 1, lookingin the direction inwhich the arrows point.

Figure 4 is a fragmentary elevation of one of a group of foldable ordouble sheets of the invention.

Figure 5 is a similar view of another or a second group of double offoldable sheets of the invention.

Referring to the drawing, in connection with which like characters ofreference will designate corresponding parts throughout, the improvedticle comprises a plurality of double leaves, pages, etc., certain ofwhich are designated by the numeral I, andothers by the numeral 2. Allof these double leaves consist of sheets of material each havingintermediately arranged and longl: tudinally disposed fold lines adaptedto be folded as indicated in Figures 2 and 3 in relatively collated ornested arrangement, as is also shown in said Figures 2 and 3.Thefoldable sheets I are each formed with a longitudinally disposed slotor way 3 along and longitudinally of their respective fold lines. Saidslots or ways 3 each terminate in inwardly spaced relation to theadjacent transversal edges of their respective sheets, as illustrated inFigure 4, and each are formed with fingers or lips 4 projecting fordistances into and longitudinally of their respective slots or ways 3.Longitudinally disposed fold lines 5 and 6 are formed or provided uponthose portions of the foldable sheets I outwardly of their respectiveslots 3; it being noted that the fold lines 5 longitudinally coincidewith the opposite sides of the fingers 4 and that the fold lines 6,parallel to the fold lines 5, are medially arranged with respect tosaidffingers 4 and extend to the adjacent marginal edges of said sheetsI. 1

The foldable sheets 2 are formed with longitudinally opposed Ways 1along their respective fold lines, which, as will be noted uponreference to Figure 5, open onto the opposite transversal marginalportions of the sheets 2 and extend inwardly with respect to such sheetsfor distances approximately corresponding to the distances occurringbetween the opposite ends of the slots or ways 3 of the sheets I totheir particular transversal marginal portions.

To efiect binding of the sheets I and 2 into book, magazine or similararticle formation, these sheets are collated or assembled in relativelyoverlying or nested relationship, as shown in Figures 2 and 3. Thelongitudinally opposed and intermediate portions of the sheets I arefolded inwardly along the fold lines 5 and, obviously, reversely foldedalong the fold lines 6 and hence, providing each of said sheets withinwardly extending cross-sectionally V-shaped portions now designatedfor convenience by the numeral 8. The inwardly disposed portions 8 ofthe sheets I are engaged through the adjacent ways 1 of the sheets 2,and it will be here noted that the respective widths of said Ways 1 aresuch that with folding of said portions 8, as shown in Figures 2 and 8ofthe accompanying drawing, they will be rather snugly received throughtheir adjacent ways 1. With the portions 8 thus engaged in or throughthe ways 1 of the sheets 2, it will be observed, upon reference toFigure 1 of the drawing, that the inwardly extending finger portions 4thereof will overlappingly engage with adjacent portions of the sheets 2along or in proximity to their respective fold lines. To facilitate suchoverlapping engagement of the fingers 4 of the portions 8 with respectto the sheets 2, the latter may be outwardly flexed sufliciently toallow said fingers 4 to be slipped or moved thereover intosaidoverlapping arrangement or, if desired, the fin '"tions' andextendinginwardly for predetermined gers 4 themselves may be bent orflexed so as to of the ways in said first mentioned sheets, the inwardlydisposed V-shaped folded fingers and the portions adjacent thereto beingreceived through the ways of the second sheets and having portionsengaged over adjacent portions of the latter along their fold lines.

2. An article of the character described, comprising longitudinallyfolded sheets, relatively spaced inwardly disposed longitudinally foldedportions on certain of said sheets substantially parallel with and inproximity to their fold lines,

, each of said portions having an inwardly disposed facilitate theirpassage through the aligned ways portions of the sheets 2.

The assembled sheets I and 2, interconnected;

asabove described, are now fiatlyfoldedfinto book, pamphlet or magazinearrangement or iormation. V i Should it be desired to, remove certain ofthe sheets I or 2 from the self-bound article, as above, the fingers 4of the inwardly disposed portions 8 may be disengaged from over theadja-, cent portions of the sheets 2 and in this way; said sheets I and2 will be disconnected upon withdrawal of the portions 8 fromthe-adjacent ways 1 of the sheets 2. Thereupon, the particularly desiredsheets I or 2 may be removed from the assembly, whereupon the remaining.sheets will be re-assembl'ed and reconnected or bound, in the mannerhereinbefore described.- By the same'token, it will be understood thatadditional sheets I or 2 may be added to a previously constituted boundbook, pamphlet, magazine or like article. That is to say, suchadditional sheets will be in the form of either the sheets I or 2 of theoriginal assembly and will be accordingly included and bound orinterconnected in the article assembly. ,I-claim: v I

.-1'. An article of the character described, comprising longitudinallyfolded sheets, certain of which have ways formed therein along theirfold lines terminating in spaced relation to the transversal edges ofsaid sheets, relatively opposed inwardly extending fingers on saidsheets adjacent their fold lines extending into the opposite ends ofsaid ways, said fingers and adjacent outer portions of their respectivesheetsbeing folded inwardly into substantially cross-sectionally vshapedformations, and others of the sheets having relatively spaced andopposed ways therein opening onto their transversal edge portions andextending inwardly along their respective fold lines to points inproximity to theopposite ends longitudinally folded finger thereon, andothers of .said sheets having relatively spaced ways formed thereinopening onto their transversal edge pordistances along their respectivefold lines, said inwardly disposed'portions and fingers being receivedthrough the ways of the second mentioned sheets and the fingers thereonengaged over adjacentportions of the latter along their fold lines.

3. article of the character described, comprising longitudinally foldedsheets having rela': tively spaced ways formed therein opening ontotheir transversal edge portions and extending inwardly for predetermineddistances along their respective fold lines, other longitudinally foldedsheets adjacent said first sheets and arranged outwardly with respectthereto, and relatively opposed and spaced inwardly disposed portions onthe inner marginal portions of each said second mentioned sheets, eachof said portions having an inwardly extending finger thereon, and saidinwardly disposed portions and their respective fingers being receivedthroughthe ways of the first mentioned sheets and having the fingersthereon engaged over and along adjacent por tions of the latter alongtheir fold lines.

4. An article of the character described, comprising juxtaposedlongitudinally folded sheets, certain of said sheets having relativelyspaced ways formed therein opening onto their transversal edge portionsand extending inwardly for predetermined distances along theirrespective fold lines, others of said sheets, outwardly of said firstmentioned sheets, having relatively opposed and spaced inwardly foldedsubstantially crosssectionally V-shaped portions thereon substantiallyparallel with and in proximity to their respective fold lines, each ofsaid V-shaped portions having alateral inwardly extending finger onitsinnerextremity, and said V-shaped portions and fingers being receivedthrough the ways of..the first mentioned sheets and having the fingersthereon engaged over andalong adjacent portions of the latter alongtheir'respective fold lines.
